Understanding Attitude Scales and Their Characteristics

The question asks us to match different types of attitude measurement scales with their defining characteristics. Understanding these scales is crucial in survey design and market research.

Let's analyze each scale type and its corresponding characteristic based on the correct match provided:

• Arbitrary Scale (A): This type of scale is constructed in an ad-hoc manner. The selection of items is made by the researcher based on their own judgment, or 'a priori' basis, meaning based on theoretical assumption rather than empirical testing for item validity or reliability beforehand. Therefore, it matches with characteristic IV.
• Thurstone Scale (B): Also known as the Scale of Equal Appearing Intervals. In this method, a large number of statements relevant to the attitude are collected, and then judges are asked to rate the statements based on how favourable or unfavourable they are towards the attitude object. The statements finally included in the scale are those where judges show high agreement on their favourability rating. Thus, attitude statements are decided by judges. This matches with characteristic I.
• Likert Scale (C): This is one of the most commonly used scales. Respondents are presented with a series of statements about an attitude object and are asked to indicate their level of agreement or disagreement on a scale (e.g., Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree). Each response option is assigned a numerical value, and the total score for a respondent is obtained by summing up the ratings across all statements. This method uses 'summated ratings'. This matches with characteristic II.
• Semantic Differential (D): This scale is used to measure the connotative meaning of concepts. It typically uses a seven-point scale anchored by bipolar adjectives at each end (e.g., Good - Bad, Strong - Weak, Active - Passive). Respondents rate the concept on each of these bipolar dimensions by marking a position along the scale. This involves seven spaces between two bipolar adjectives. This matches with characteristic III.

Let's summarize the correct matching in a table:

Comparing this matching with the given options, we find that the combination A - IV, B - I, C - II, D - III corresponds to the correct answer.

Additional Information on Attitude Measurement Scales

Attitude scales are essential tools in social science research, marketing, and psychology to quantify people's feelings, beliefs, and opinions towards a particular object, person, issue, or idea. While the scales listed above are common, there are other methods as well, each with its own strengths and limitations regarding construction, reliability, validity, and ease of administration.

Factors influencing the choice of scale include the nature of the attitude being measured, the target audience, the required precision, and resources available for scale development. For instance, the Thurstone scale is considered more precise in determining the "equal appearing intervals" between points on the scale but is labor-intensive to construct due to the reliance on judges. The Likert scale is relatively easier to construct and widely used, assuming that each item measures the same underlying attitude and that the intervals between categories (like "Agree" and "Strongly Agree") are equal, which is often an assumption rather than a tested fact. The Semantic Differential is particularly useful for measuring the emotional or affective dimension of a concept.
